Upconversion through an HTPC over a Dvd Player

[Moontrash]

I was wondering if the up-conversion through a dvd player through an HDMI connection will look the same through an HTPC hdmi.

I have a dvd player which I use the HDMI out to an LCD and the up-conversion on newer films looks very good. Will I get the same result with an HTPC? I'm pretty sure for dvd's I'll be using MPC Home Cinema but I'm not sure if it will look the same (in terms of quality) as the HDMI out on the dvd player.

Any thoughts?

Yes, but you will spend days to keep tweaking the settings... Use madvr, lavfilters and play with mpchc.

when i decided to build this htpc i did a lot of reading and not too long ago i noticed LAVfilters and I decided I would install it instead of any codec pack and see what kind of functionality i would get. I don't mind using ffdshow but I want to see how LAVfilters does.

should I install madvr alongside lavfilters or no?

There are three not two basic signal paths with variables in each.

1. DVD/Blu-Ray players use hardware deinterlace/upscale chips and performance varies. The quality in recent Blu-Ray player chip sets is very good and modes are mostly adaptive and automatic.

2. HTPC software deinterlace is mostly Yadif which has compromise for CPU loading even though ample memory is available. Upscale filtering is also limited by CPU performance.

3. HTPC software player with DXVA/etc calls on the display card chipset for decode, deinterlace and scaling provides hardware assist to the CPU. In theory, NVidia and ATI/AMD should be able to access similar technology to the Blu-Ray players but IMO, the drivers and player tuning are less optimized than what you get from a good hardware player.
